The Straub Push-In Flex Coupling enables connections for a vast range of pipe diameters, pipe materials, media, temperatures, and operating pressures.
A progressive sealing effect increases the force on the sealing lips as the pressure in the pipe increases. The anchoring and sealing functions are also independent from each other, giving the pipework flexibility at every joint.
Straub Push-In Flex Couplings can be used on plain-ended pipes without any modifications. They can also be detached for storage or reuse.
